ww w . mccsemi .com note: 1. tolerance and type number designation. the type numbers listed have a standard tolerance on the nominal zener voltage of 5%. 2. specials available include: a. nominal zener voltages between the voltages shown and tighter voltage tolerances. b. matched sets. 3. zener voltage (v z ) measurement. guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (t l ) at 30 o c, from the diode body. 4. zener impedance (z z ) derivation. the zener impedance is derived from the 60 cycle ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (i zt or i zk ) is superimposed on i zt or i zk . 5. surge current (i r ) non-repetitive. the rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge curr ent of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current, i zt , per jedec registration; however, actual device capability is as described in figure 5. mm s z5221 b th ru mm s z52 59 b mcc electrical characteristics @ 25 o c unless otherwise specified normal zener voltage vz@ izt test current izt maximum zener impedance ?b? suffix only zzt @ izt zzk @ izk=0.25ma maximum reverse leakage current ir @ vr maximum zener voltage temp coefficient ?b? suffix only mcc part number marking volts ma ohms ohms ua volts %/ o c mm s z5221 b c1 2.4 20 30 1200 100 1.0 - 0.085 mm s z5222 b c2 2.5 20 30 1250 100 1.0 - 0.085 mm s z5223 b c3 2.7 20 30 1300 75 1.0 - 0.080 mm s z5225 b c5 3.0 20 29 1600 50 1.0 - 0.075 mm s z5226 b d1 3.3 20 28 1600 25 1.0 - 0.070 mm s z5227 b d2 3.6 20 24 1700 15 1.0 - 0.065 mm s z5228 b d3 3.9 20 23 1900 10 1.0 - 0.060 mm s z5229 b d4 4.3 20 22 2000 5.0 1.0 0.055 mm s z5230 b d5 4.7 20 19 1900 5.0 2.0 0.030 mm s z5231 b e1 5.1 20 17 1600 5.0 2.0 0.030 mm s z5232 b e2 5.6 20 11 1600 5.0 3.0 +0.038 mm s z5234 b e4 6.2 20 7.0 1000 5.0 4.0 +0.045 mm s z5235 b e5 6.8 20 5.0 750 3.0 5.0 +0.050 mm s z5236 b f1 7.5 20 6.0 500 3.0 6.0 +0.058 mm s z5237 b f2 8.2 20 8.0 500 3.0 6.5 +0.062 mm s z5239 b f4 9.1 20 10 600 3.0 7.0 +0.068 mm s z5240 b f5 10 20 17 600 3.0 8.0 +0.075 mm s z5241 b h1 11 20 22 600 2.0 8.4 +0.076 mm s z5242 b h2 12 20 30 600 1.0 9.1 +0.077 mm s z5243 b h3 13 9.5 13 600 0.5 9.9 +0.079 mm s z5245 b h5 15 8.5 16 600 0.1 11 +0.082 mm s z5246 b j1 16 7.8 17 600 0.1 12 +0.083 mm s z5248 b j3 18 7.0 21 600 0.1 14 +0.085 mm s z5250 b j5 20 6.2 25 600 0.1 15 +0.086 mm s z5251 b k1 22 5.6 29 600 0.1 17 +0.087 mm s z5252 b k2 2 4 5.2 33 600 0.1 18 +0.088 mm s z5254 b k4 27 4.6 41 600 0.1 21 +0.090 mm s z5255 b k5 28 4.5 44 600 0.1 21 +0.091 mm s z5256 b m1 30 4.2 49 600 0.1 23 +0.091 mm s z5257 b m2 33 3.8 58 700 0.1 25 +0.092 mm s z5258 b m3 36 3.4 70 700 0.1 27 +0.093 mm s z5259 b m4 39 3 .2 80 800 0.1 30 +0.094
